C. Tides Tides are created because the Earth and the moon are attracted to each other, just like magnets are attracted to each other. The moon tries to pull at anything on the Earth to bring it closer. But, the Earth is able to hold onto everything except the water. Since the water is always moving, the Earth cannot hold onto it, and the moon is able to pull at it

Any idea why the place on Earth facing away from the moon also has a high tide?

The water of the entire world ocean is pulled by the moon's gravity. On the opposite side of the earth simultaneously there is a high tide due to the inertia of the ocean water and because the earth is being pulled toward the moon by its gravitational field yet the ocean water remains left behind. This creates a high tide on the side of the earth opposite the high tide caused by the direct pull of the moon.

Thanks ramkrishna!
I have seen that answer somewhere before, but you have a reference. Still, I would appreciate a mathematical treatment. I can't really grasp how this can really happen. I wonder if moon's gravity gradient has something to do with this!

yes also on the other side of earth there is low gravity than the front side of earth it also enhances the tide toward other side of earth.
